We build the hardware and install the system
Residential · Detached house, single-phase supply
This is the shape most homes start with: one inverter, one battery, one meter, and enough usable energy to move the expensive part of the day off the grid. It is an entry point rather than a compromise — the pack is built to be joined by fifteen more on the same bus without replacing anything already on the wall.
What this shape answers
The house draws most of its electricity between four and ten in the evening, when it is dearest and the roof has stopped producing.
A short cut takes the router, the freezer and the boiler controls with it.
Budget rules out oversizing on day one, so whatever goes in has to extend later without being scrapped.
Configuration
Values are taken from the datasheet of each part named. Where a published datasheet and this page ever disagree, the datasheet is correct.
Bill of materials
Catalogue parts link to their own datasheet page. Assemblies marked built to order are manufactured against your schedule and carry no fixed SKU.
Add up to fifteen more later on the same bus.

Scope of works
We measure the supply, read the meter data and photograph the board before anyone draws anything. Most of what changes a design is found in that hour.
A single-line diagram, the position of every box marked on a photograph of your wall, and a fixed price with no provisional sums.
Storage that can export has to be declared to the network operator. We prepare the paperwork and submit it; you do not chase it.
One or two days on site at this size. The supply is off for part of one of them, and we tell you which part before the van arrives.
Charge and discharge proved against the meter, backup circuits proved by pulling the main switch, and every setting we leave the inverter on written down.
Generation, consumption and state of charge on your phone. We look at the same data when you call, which is why most questions do not need a visit.
Handover pack
Read this first
This is a reference design, not a record of delivered work. It names no client and publishes no measured outcome, because we have none to publish yet. Every quantity comes from a datasheet; nothing has been worked backwards from a claim.
Next design
10 kW across three phases, 16.07 kWh of storage, and a charger that waits for the roof instead of the clock.
Your site
Supply type, a photograph of the board and a year of meter data is enough for us to tell you which of these fits.
